sum 1 BF 2 RED ORANGE YELLOW GREEN BL UE IND/60 VIOLET 1 KEYBOARDACTUATED LIGHTING INSTRUMENT BACKGROUND OF THE INVENTION This inventionrelates to a lighting instrument which is operated by switches, and moreparticularly, to a panel keyboard operated lighting instrument.Accordingly, the general objects of this invention are to provide newand improved devices of such character.

The imvention relates to a panel keyboard actuated lighting instrumentwhich can be operated by an operator having a musical background so asto play the lighting instrument in conjunction with the musical lightingscore.

The invention, though ostensibly relating to the field of color optics,functions in a language-music-color synthesis which is authored andcreated by the applicant in a book entitled The Tonaligua- ConcordophoneSystem of Color-Music Composition, published and copyrighted in 1972.Description is also provided in a book authored by the applicant,entitled Tonachromaton-Creating Electronic Color-Chord P t thr s,-ansysei. to be nyh shesiin 3.. A Tonalingua Chordmaster Set waspatented by the applicant July 27, 1965 as US. Pat. No. 3,196,732.

The present invention constitutes an apparatus for effecting the colorcomposition aspect of the foregoing system. In view of its orientationin a multimedia synthesis, a brief description of the TonaliguaConcordophone system is described hereinbelow.

The Tonalingua Concordophone system is the result of three concepts: (1)verbalization of chord intervals (Tonalingua), first described in thebook Tonalingua and the Inner M273, Pub ish??? andrqgr he 1957 by theapplicant, (2) establishment of a scientificbasis for correlating colorwith harmony (Concordophone), and (3) creation of a system whereby thedesired chord words (translated into their tonal equivalence) areretrieved from a source tape, fed into a second tape recorder, and thencorrelated with a color organ device (the Tonachromaton).

The language-color-music synthesis broadens the foundations of aestheticself-expression and heightens aesthetic pleasure by correlatingwhat isheard by the ear with what is seen by the eye. This system of harmonycomposition through -Tonachromaton" is geared to immediate conversion ofexpressive desires into tonal-color texture. This invention opens up theworld of music to those unskilled in the art of composition and unableto play a'keyboard musical instrument. By merely following a few simpleinstructions on how to identify Tonalingua] notation (for tape retrievalpurposes), as well as a few basic harmonic grammar rules, the art ormusic hobbyist has access to, and control of, a tremendous potential formultimedia expressiveness.

In the Tonalingua-Concordophone system, the individual thinks of colorand then transposes this into letters and in numerical system. Thechoice of colors may stem from apoem, abstracting from a rememberedexperience, the colors suggested by that experience, or the colorselections could be based on a particular mood the individual happens tobe in when commencing the color-music creativity experience. Regardlessof how the choice is made, each color selection is integrated with thetonal medium to a lexicon of chord pairs (in Tonalingual notation), eachof which represents a certain color appearing in a metaphoricalorientation of a Harmony Star." This metaphorical orientation isembodied in the design of the Light Compass.

In the display structure of the Light Compass, the inner circle colors(red, orange, yellow, green, blue, indigo, and violet) reflect theinterval relationship produced by the outer tones (soprano and bass) ofa given chord pair. The colors of the outer segment reflect the intervalrelationship produced by the inner tones of a given chord pair.

Organization of color-harmony resources around the points of-the compasshave a three fold purpose: (1) to vivify the inner space environment ofwhich creativity takes place by intensifying the spatial concentricorientation of the harmony star concept, (2) to make possible in thisgeographical orientation a greater potential for maximizing power tovisualize images intensely, and (3) to further enhance the potential forartistic expressiveness by broadening the symbolic horizons. Thermalimagery, for example, is given an added dimension of reality byactuating the North Arc (ice) or the South Arc whose purple hues suggestwarmth.

DESCRIPTION OF PRIOR ART During the course of a preliminary noveltysearch, performed on behalf of the applicant, the following UnitedStates Patents were listed which may be of interest.

Inventor US. Pat. No. Issue Date Kingsley 1,401,608 Dec. 27, 192i Hector1,432,553 Oct. l7, I922 Vinageras 1,577,854 Mar. 23, l926 Beers1,669,117 May 8, 1928 Hector 1,728,860 Sept. l7, 1929 Craig l,790,903Feb. 3, I93! Wortman 3,228,278 .lan. ll, 1966 Kingsley disclosesilluminating attachments for keyboard musical instruments. Hisattachment has a set of switches with their actuators arranged in suchposition that they may be operated by a player while his fingers are onthe keys of the piano or organ, and control circuits to suitableelectric lamps of various colors. Kingsleys switch actuators are solocated that they may be operated by the thumbs of the player while hisfingers are on the keys. 'Thus,'the player is able to flood the regionaround the piano with an illumination of a color and an intensity whichhe deems mostappropriate for the particular tones, chords,'motifs, ormusical figures being produced at that time. Kingsleys lamps are locatedat the side of a stage and are intended and directed to illuminate thestage with various colors. Kingsley does not describe nor suggest aninstrument which provides a feeling of motion of the various colors.

Hector, US. Pat. No. 1,432,553, discloses other lighting arrangementsoperated by a keyboard instrument. Hector discloses a series of lampswhich may be provided with differently colored globes, or may beenclosed by polished, parabolic reflectors in front of which are placedcolored screens of varying hues. The lamps are made to project on a dullwhite surface to project diffusion of the colors. Alternatively, thelamps may be made to project their colored lights on semiopaque glassstructures, such as a gothic church window. The light may be transmittedthrough semiopaque glass, or the glass may be silvered and the lightreflected. The order of the colors displayed by Hectors device arecoupled with respect to the note scale. of the keys of an instrument andare arranged to correspond to the arrangement of colors in a doublerainbow,,the violets being at one end of the scale and the reds in themiddle, and the colors displayed by the devices controlled by the bassnotes being of darker hues than those corresponding to the treble notes.Hector, US. Pat. No. 1,432,553, does not suggest that a color music"device'which contains its own notes or can be controlled independentlyfrom musical notes.

Vinageras discloses lighting in a cylinder with the use of differentcolored projection lights and explanations of concentric arrangements.Vinageras discloses a chromopiano, utilizing color notes composed andwritten in a manner analagous to that in which sequences and chords ofmusical notes are composed and written, with the intention of playinghis chromopiano" tuned in unison with the instruments of an orchestra inwhich the movement of the chromopiano is synchronized with the movementof a player piano, an organ, or a phonograph and to have them playtogether automatically. The source of light of Vinageras is anincandescent lamp or arc lamp wherein his chromopiano utilizes as manylamps as projection holes. Although Vinageras states that three colornote chords can be produced, when chromomusical chords with more thanthree color notes are desired, chromopiano is provided with moreprojection holes and more keys.

ln contradistinction, applicants Concordophone Light Compass does notoperate on a physicomathematical basis as does the chromopiano ofVinageras. Applicants system of sound-color correlation is entirelydifferent, wherein his Light Compass is based on mathematicalrelationships which stem from the semitone motion differential existingin the movement of the tones of one chord to the tones of another. Agiven pattern of semi-tone motion between any two chords produces aspecific color. The same color is produced, furthermore, in differentpairs of chords providing the semitone motion differential remainsidentical. The mathematics of proportion and permutation underlie thevarious patterns of movement which are produced. Another feature whichdifferentiates applicants Light Compass from the Vinageras Chromopianois that the latter instrument projects light by means of lenses,whereas, applicants Light Compass produces various colored lightsdirectly when buttons on the panel are depressed. Vinageras is based onthe electromagnetic application of light, whereby the entire orientationas well as the color effect is different from that produced byapplicants light compass. Disadvantageously, the Vinageras device wouldrequire the performance thereof by a professional musician withconsiderable background in a science of color combinations, ascontrasted with the application of applicants Light Compass which can bereadily played by a layman. Another distinction is that Vinageras isdirected to illuminating stages, halls, etc. and, when tuned to unisonwith musical instruments, the combination of devices as used to presenta finished work. On the other hand, applicants Light Compass is a devicefor the layman to translate, into color patterns, the chord progressionshe has composed in the Tonalingua- Concordophone system. In short,Vinageras device is not integrated with a system of musical composition.Applicants Concordophone Light Compass, on the other hand, forms anintegral part of a system of composition designed primarily for themusic or art hobbyist, as wellas for the poetry enthusiast interested increating colored chord interpretations of poetic works.

Beers discloses a circular arrangement of lights controlled by astringed instrument, but does not suggest, however, an independentlycontrolled lighting device.

Hector, US. Pat. No. 1,728,860, shows colored lights arranged in acircle or logarithmic spiral and controlled by a keyboard instrumentmeans along with means for defusing the light, suggesting, however, thatthere may be instances where a silent keyboard (that is, without theagency of sound) is used to produce luminous displays.

Craig discloses a circular arrangement of colored lights shining on atranslucent screen, but not key operated, the colors being activated bymusical tones broadcast from a radio.

Wortman shows a circular arrangement of lights and panel surfaces foruse therewith, which is activated by means of frequencies and amplitudescoming from a speaker system to show the various colors.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, there isShown a diagram of the various colors that are selectively actuated inaccordance with this invention. The diagram includes a pair ofconcentric circles 10 and 11. The inner concentric circle can beselectively actuated toproduce lights of various colors, such as red,orange, yellow, green, blue, indigo, and violet. The outer concentricring formed by the concentric circles 10 and 11 are divided into aplurality of sectors l2, 13, 14, l5, 16, 17, 18, 19, 20, and 21, asshown in FIG. 1, the numerals 12 through 21 being oriented clockwisewithin the drawing. The various sectors can be designated by variousdirectional components, such as north, south, east, west, southwest,northeastf northwest, southeast, and northnortheast and north-northwest,the upper sector 12 of the circle being located in the north directionand the lowe portion being in the southerly direction. Separate colorsare provided within the various sectors 12 through 21 as follows: Sector12 in the north direction is ice, Sector 13 in the north-northeastdirection is incandescent, Sector 14 in the northeast direction isamber, Sector 15 in the east direction is gold, Sector 16 in thesoutheast direction is blue, Sector 17 in the south direction is violet,Sector 18 in the southwest direction is green, Sector 19 in the westdirection is red, Sector 20 in the northwest directon is cobalt, andSector 21 in the north-northwest direction is somber.

It will be noted that the colors in FIG. 1 that are in the so-callednorthern hemisphere are of cool coloration, whereas, the colors in thesouthern hemisphere are of a warmer direction. Technically, the colorsin the upper half of the semi-circle are cool and the lower semi-circleare warm. However, when viewing the color diagram of FIG. 1, it ishelpful to consider the configuration as being one of global orientationwhereby ice is located at the north pole. Various ones of the sectors 12through 21 are selectively activated so that a single sector at a timeis illuminated. This single sector can be illuminated simultaneouslywith one of the seven colors within the central circle 10.

In operation, various ones of the colors about the sectors 12 through 21are activated simultaneously with various ones of the colors within thecentral circle 10 in a rhythmic fashion somewhat in the nature of music.The colors are activated independently of musical notes, per se, but aredesirably activated in accordance with lighting notes, so to speak.

FIG. 2 is a front perspective view of a lighting instrument 26 inaccordance with one embodiment of this invention. The lightinginstrument 26 is generally drumlike in shape and includes a translucentscreen 27 which is circular in shape and is adapted to have lightprojected thereon in accordance with the color diagram of FIG. 1. Thelighting instrument 26 may have suitable legs 127-127 at its base and ahandle 28 at its top. A rear perspective view is also shown in FIG. 3.

Suitable switches 29-29 are provided at thev rear of the lightinginstrument 26 for actuating various different colored lamps within thecentral circle 10, whereas, other switches 30-30 are located at the rearof the instrument 26 for actuating various colored lamps between theconcentric circles 10 and 11 to selectively actuate colored lamps,respectively, for the various sectors 12 through 21. The switches 29-29,30-30 are mounted at the rear of the instrument 26, either as buttonsdirectly connected to the panel, or on a separate adjacent panelkeyboard. An electrical cable 32 is coupled to the lighting instrument26.

Referring to FIG. 5, the lighting instrument 26 includes an outercylindrical housing 36 and an inner concentric cylindrical housing 37.The cylindrical housing 36 and the concentric housing 37 have one end,respectively, coupled to a translucent screen 27, as shown in FIG. 4.The outer housing 36 is coupled to the inner housing 37 by variouspartitioning members 40, 41, 42, 43, 44, 45,46, 47, 48, and 49 in suchfashion as to form the various sectors 12 through 21 respectively.Within the various sectors 12 through 21 are located a plurality ofvarious colored lamps 50, 51, 52, 53, 54, 55, 56, 57, 58, and 59,respectively. The colored lamps 50 through 59 are lamps for producingcolors ranging from ice through somber, respectively. A plurality ofcolored lamps 61, 62, 63, 64, 65, 66, and 67 for producing colors ofred, orange, yellow, green, blue, indigo, and violet, respectively, arelocated within the inner concentric housing 37.

One terminal of each of the lamps 50 through 59, inclusive, and each ofthe lamps 61 through67, inclusive, is coupled to a common lead 70, asshown in both FIGS. and 6. 1

The other terminal of each of the lamps 50 through 59 are coupled to oneside of their respective switches 30, 30 and shown in FIG. 3, and asindicated in FIG. 5. In a similar fashion, the other terminals of thelamps 61 through 67 respectively, are coupled to one terminal of therespective switches 29-29, respectively, as indicated at FIGS. 3 and 5.

The remaining terminals of all the switches 30-30 and 29-29 are coupledto a common lead 71 as indicated at FIGS. 5 and 6. The leads 70 and 71are coupled via a cable 32 to an electrical plug 72. The electricalplug72 can be coupled to an electrical potential source such as 1 volts a.c.or other desirable electrical source.

In operation, it will be noted that the light instrument 26 is portable.It can be carried by the handle 28 and placed upon a stage (not shown)by resting the instrument upon the pedestals 127 upon the floor of thestage. The player, may sit on a chair (not shown) and, after placing theelectrical plug 72 into a suitable receptacle, he may selectivelyactuate the switches 29 and 30 in accordance with a suitable score whichmay be tied in with a musical arrangement. The player, in a timedsequence, suitably depresses various ones of the switches 29 and 30 toactuate various ones of the lamps within the sectors 12 through 21,respectively, and the lamps within the inner concentric housing 10,producing colors within the central housing ranging from red throughviolet and producing colors about the outer sectors ice through somber.

In addition to producing various colors selectively at the innerconcentric circle 10, the player produces various colorsselectively'about the outer concentric circle, but, in addition toproducing colors about the outer concentric circle, the playerselectively actuates the colors at various selective positions about theouter concentric circle. Hence, the player is not merely illuminating,say, red, at the inner circle, and gold at the outer circle, butactually is producing the color red at the inner circle (if he sodesires), but he produces the color gold at the easterly direction.Hence, in a sense, applicants invention is a light compass in thatcolors are produced in accordance with desired orientations and notmerely colors in a random directional manner. Hence, musically, theplayer may produce variations in colors, ranging in directions fromeast, to northwest, to south, southwest, west, southeast, etc. in arhythmic manner.

Hence, with applicants invention, a light instrument has been providedthat produces not only a variation in colors, but a variation indirectional patterns in that light is produced at various portions aboutdifferent sectors of the translucent member, the translucent memberoperating somewhat as a screen or a light show.

Various modifications may be performed without departing from the spiritand scope of applicants invention. For example, although push buttonsare illustrated in FIG. 3, it will be apparent that other types ofswitches can be used, such as different types of keyboard devices.Simply, push buttons are an elemental form and a desired form ofkeyboard actuation. However, other types of keyboard actuated switchesmay be used, dependent upon the degree of ease upon which the playerdesires to actuate the various keys and depending upon the expensedesired in providing a keyboard which is more biologically suitable,such as a keyboard which can be operated by two hands independently inthe fashion of a dual typewriter setup. Other suggestions will becomeapparent to those skilled in the art.
